ROLLER.

Specification of Letters Patent.

Patented Aug. 29, 1911.

Application filed October 15, 1910. Serial No. 587,243.

To all whom it may concern:

Be it known that I, Jnssn S'roRoK, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented new and useful Improvements in Rollers, ofwhich the following is a specification.

This invention relates to rollers and more particularly to that typewhich are adapted to be used as trucks for the transportation of heavyarticles such as logs, machinery, crates, etc. Heretofore in moving logsor the like it was customary to place a plurality of rollers beneath thesame which had to be picked up as the tail end of the log passed overthe same and placed under the forward end. This operation had to berepeated many times according to the distance the log was moved and itis the object of this invention to provide a supporting roller by whichlogs may be moved any distance without altering the initial position ofthe roller beneath the log.

A further object of the invention is to provide a roller of thischaracter which will be compact and which will have very little heightso as to obviate raising the log or other article any great distance.

Further objects of the invention will appear as the following specificdescription is read in connection with the accompanying drawing whichforms a part of this application, and in which:

Figure 1 is a side elevation. Fig. 2 is a bottom plan view. Fig. 3 is alongitudinal section. Fig. 4 is a transverse section. Fig. 5 is aperspective view of the shaft removed from the roller.

In the specific embodiment of the invention illustrated herein I haveshown a shaft 1 having a central collar 2 arranged thereon and endcollars 3. Where the roller is shorter the intermediate collar 2 will beomitted and if the roller is desired longer than the one shown morecollars will be interposed throughout the length of the shaft toseparate the rolls 4. The collars 2 and 3 are provided with recesses 5forming diawhich the rollers 4 are mounted, the end thrust of saidrollers 4; being taken against the ends 7 and the intermediate web 8. Inorder to hold the shaft in position within the shelf member, bearingbrackets 13 are secured across the ends and held in place by suitablebolts, lag screws or the like. As shown in side elevation the rollersproject only a sufiicient distance below the lower edge of the shelf toraise the same above the ground and to prevent contact thereof withsmall obstructions on the ground.

Having thus described the invention, what is claimed is .A device of theclass described comprising a shelf having a semi-cylindrical recess,recessed end members on the shelf, an intermediate web connecting thesides of the shelf and having a recess therein, a shaft having aplurality of collars with square sides seating in said recesses of theend members, and the web, anti-friction devices arranged on said shaftbetween the collars, supporting rollers arranged on said antifrictiondevices and projecting below the lower edge of said shelf, said rollersarranged between said end members and web, and means carried bythe endmembers for securing the shaft in the recesses of the end members andweb.

In testimony whereof I affix my signature in presence of two witnesses.
